Sorry I am just getting to this. I actually have an easy fix for this,
and it is a feature of entab:

$ entab -h
USAGE: entab [ -cdqst ] [file ...]
-c (clip trailing whitespace)
-d (delete tabs)
-q (protect quotes)
-s minimum_spaces
-t tab_width

-s minimum_spaces defaults to 2, and pgindent doesn't change the
default. If we change the entab call in pgindent from

$entab -t4 -qc

to

$entab -t4 -qc -s3

we will no longer place a tab in this string, "friend. Hopefully"

even if there is a tab stop before the 'H'. It will use a 3-space
break. Does that help? Other ideas? How about requiring 4?
